| 1 | Physics-informed deep learning for incompressible laminar flows显示文摘Physics-informed deep learning has drawn tremendous interest in recent years to solve computational physics problems,whose basic concept is to embed physical laws to constrain/inform neural networks,with the need of less data for training a reliable model.This can be achieved by incorporating the residual of physics equations into the loss function.Through minimizing the loss function,the network could approximate the solution.In this paper,we propose a mixed-variable scheme of physics-informed neural network(PINN)for fluid dynamics and apply it to simulate steady and transient laminar flows at low Reynolds numbers.A parametric study indicates that the mixed-variable scheme can improve the PINN trainability and the solution accuracy.The predicted velocity and pressure fields by the proposed PINN approach are also compared with the reference numerical solutions.Simulation results demonstrate great potential of the proposed PINN for fluid flow simulation with a high accuracy. | Chengping Rao Hao Sun Yang Liu | 2020 | Theoretical & Applied Mechanics Letters2020，10，3： | 11 |
| 2 | Numerical Simulation of the Solitary Wave Interacting with an Elastic Structure Using MPS-FEM Coupled Method显示文摘Fluid-Structure Interaction(FSI) caused by fluid impacting onto a flexible structure commonly occurs in naval architecture and ocean engineering. Research on the problem of wave-structure interaction is important to ensure the safety of offshore structures. This paper presents the Moving Particle Semi-implicit and Finite Element Coupled Method(MPS-FEM) to simulate FSI problems. The Moving Particle Semi-implicit(MPS) method is used to calculate the fluid domain, while the Finite Element Method(FEM) is used to address the structure domain. The scheme for the coupling of MPS and FEM is introduced first. Then, numerical validation and convergent study are performed to verify the accuracy of the solver for solitary wave generation and FSI problems. The interaction between the solitary wave and an elastic structure is investigated by using the MPS-FEM coupled method. | Chengping Rao Youlin Zhang Decheng Wan | 2017 | Journal of Marine Science and Application2017，16，4： | 2 |
| 3 | Nickel-Catalyzed Cross-Electrophile Coupling of Triazine Esters with Aryl Bromides显示文摘Cross-electrophile coupling of triazine esters with aryl bromides could be facilely accomplished by employing nickel as catalyst,magnesium as metal mediator,and lithium chloride as additive.The reactions proceeded efficiently in THF at room temperature through C—O bond activation to afford an array of structurally different diaryl ketones in moderate to good yields with wide functional group tolerance.Control experiments showed that nickel,magnesium,lithium chloride,and THF are all indispensable for the good performance of the coupling reaction.Preliminary mechanistic exploration indicated that in situ formed arylmagnesium reagent by the insertion of magnesium into aryl bromide might serve as the key intermediate of the cross-coupling.The method which avoids the utilization of moisture-labile and relatively difficult-to-obtain organometallics is step-economical,cost-efficient,and operationally simple,potentially serving as an attractive alternative to documented methods. | Xiang Liu Cai-Yu He Hao-Nan Yin Chengping Miao Xue-Qiang Chu Weidong Rao Hao Xu Xiaocong Zhou Zhi-Liang Shen | 2023 | Chinese Journal of Chemistry2023，41，24： | 0 |
